placed upon the door. and uponthe jamb;

It. is the usual custom to place two sets of butts upon each hinging, but I have provided means inmy door but't'gauge for the locating oftwo or more of the same to be done at one tinieand from one set up of the device,';to enable the user of the same to mark the doorand the jamb. Each tolbe markedpreciselyfas the other. A further object of my .invention, consists inxa fabricated frame structure where inthe sa'me maybe disassembled and placed in'the ordinary carpenters tool box'and to not be of a greaterlength thanthe tools as ordinarily carried therein; j

A furtherobject of my invention, consists in having blades placed therein which said blades may berenewed frointime. to time, or removed and sharpened and replaced within the marking heads. A further'object of my invention, consists in the same being made of but few parts and of simple construction, and a door butt gz'iuge that may be. used by any ordinary workman not skilled in this kind of work. 7

Vith these and incidental objects in View,

the invention consists in certain novel fea-V tures of construction and combination of part-s, the essential elements of which are set forth intheiappended claims, and a preferred'form of embodiment of which is hereinafter shown with reference to the drawiii-gs whichaccompany and form a part of this specification; I I

Like, reference. characters refer to like partsthroughout the several views. I

1. is. thedoor casing, having a header 2, placed thereupon. My device is composed of one or. more sections, as shown as, thesam'e being jointed together by any suitable telescopic fastening means, as shown at-4, and having'disposed upon the upper end thereof an engaging stop. 5, said stop being in ad justable relation with the frame member 3, and which may be locked to said frame memher by suitablefastening means, as screws 6, the said screws being adapted to engage. with the slot 7. The stop may be positioned and 'held in such position by a spring 8, adapted to engage within theindentures 9', the object ofwhich, is to provide the clearance between the underside of thev header 2, and the top end of the door 28. The end. lOof the stop engages on the underside of the-header 2, and the underside 11 of the stop, engages on the upper side of the door28. Where a standard space is to be provided, between the header 2, and the door 28-, the same is governed by the depth .12 of theistop. Ifa greater, or a lesser'distance is required be tween the header and the door, the same may. beregulated by. moving the stop relatively to the frame member, after the doorcasing-has been marked by the useiof my device; I have described thestop 5 as being mounted to the upper section. In actual practice, either or both end sections are provicle'clwvith a stop 5,-though I have limited myself to the description of the stop upon one end of the sectional support. Located upo nthe jointed frame members 3', area series of marking heads 13, which are in slidable relationship with the jointed frame members. The j ointed frame members have graduated markings 14, thereupon, anda'slot 15 longitudinally of thejointed frame, to maintain the marking heads in position and alignment thereupon; The marking heads in pairs are carried by an anvil head 16, "and each head has a graduated projection 17 projecting therefrom and sli'dably passin'g'through the guide bars 18,whioh permits the marking heads to be moved laterally 'o-f th'e' slotted rods 3, when the guide bars'are positioned on the rods 3 as shown. in Fig. '5. The projections '17'may he Vii held in a stationary position by means of the screws 19 which are threaded through the top or head of the guide bars 18, and engage the projections 17. On the underside of the guide bars 18 is another screw 19 having the washer 19 positioned thereon. The washer 19" has a lesser width and a greater length than the width of the slot 15, and when the same is positioned with its length transverse of the slot 15 it will maintain the guide bar 18 in sliding engagement with the bar 3, and by tightening the screw 19 the guide bar 16 can be positioned in a stationary position on the bar The anvil has one fixed marking head 20, with the end i'narking blade 21 and side blade 21, disposed on the under side thereof. On the opposite end is a dovetail projection 22, and the marking heat with the end marking blade B l and side blade 21, secured thereto in slidable relationship with the dovetail projection 22, disposed on the under side of the anvil section. This marking head 23, may be .adjustably positioned relative to the stationary head by suitablev fastening means, as screw By making the head slidablc relative to head 230, the exact length of the hinges may be marked bv the end blades 21. and Si, by sliding the head :22 to or from the head 20: and of course the width of the hinges may be marked by the blades 21 and 2 1 by positioning the projections 17 in the guide bars 18. The anvil lti, is made of substantial size and of material suitable for receiving thereupon the blow ol a lltl1'l1 mer or mallet. lVhcn the marking heads have been positioned to mark the depth or length and width of the door butt or hinge, and the device has been positioned upon the :t'ramc or door, a blow of the hammer or mallet of the workmanupon the anvil section, causes a penetration of the anvil blades into the structure to be marked.

The locator wings 9.6 are pivotally disposed upon each of the joints of the device. and when revolved in to operative posi itm have outwardly extending arms :26 which engage with the edge of the surface to be marked. These locator wings are used when the depth of butt to be marked, and this is particularly illustrated in Figs. 2 and -'l.

In practice, the locator head, as shown in Fig. ti, is placed upon the under side ot the header of the door frame. and the marking heads are set to the width oi? the door butt or gauge. and the casing is marked as best illustrated in Fig. '1. The same is then set upon the door, as best illustrated in Fig. 3, and the width of the door buttor hinge. is then marked upon the door. The instrument is then set for marking the depth of the door butt or hinge, as best illustrated in Fig. 2, and the same is marked by tapping the anvil member. to mark the depth upon the door casing. The instrument is then transferred to the door, as illustrated in Fig. 4, and the depth is then marked upon the door, after which the workman then removes the material and makes the door butt or hinge fast thereto.

\Vhile the form of mechanism herein shown and described is admirably adapted to tultill the objects primarily stated, it is to be understood that it is not intended to conline the invention to the one form of embodiinent herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

lVhat I claim is:-

l. A door butt gauge, comprising an elongated sectional frame structure, marking heads in slidable relationship with the frame structure; means for maintaining the marking heads in fixed position relative to said trame; an end stop slidably disposed upon one end of said frame, adapted to engage with the head of a door frame and the upper edge of a door, to space the top of a door from said header; and marking blades disposed within the marking heads.

in a door butt gauge, an elongated sec tional support member provided with longitudinal slots in each section; an anvil mem-- ber movable longitudinally of said support member; a marking head formed on said anvil member; a second marking head supported by said anvil member and movable relative to the first mentioned marking head; each marking head being provided with sup port means slidably engaging the a'toremem tioned slots; and incisive elements carried by each marking head.

3. A door butt gauge comprising an elongated sectional, graduated, fabricated frame structure; each section having guide slots disposed longitudii'ially thereof, marking heads slid-ably engaging with said guide slots, marking and cutter blades disposed within the marking heads, and means for positioning the gauge upon the jamb and upon the door in the same relative position.

-.l-. In a door butt gauge, the combination ot a frame composed of a plurality of elongated sections; there being a longitudinal slot formed in ach section; guide bars :Aiidably engaging said slots; means to maintain said guide bars in a stationary position along said slots; projections slidably disposed through said guide bars, means on said guide bars to position said projections; an anvil; a relatively stationary marking head and a relatively slidable marking head supporting said anvil; said marking heads each being supported by one of said projections; and means to secure the slidable marking head in a fixed position in relation to the stationary marking head.
